I have just recently started watching these videos and they are so well done and enjoyable to watch, especially from a film students perspective. Now from what I can tell, is there are either two or three videographers recording the show, one getting a wide shot on a tripod of the artists playing, and the two others focus on getting close ups of the performers faces, guitar fret boards etc. The videos are always edited together in a very clean yet creative way. The really impressive part is the audio piece. Keep in mind they are recording in a standard office. The last time I went into an office I don't remember there being acoustics like the ones in Ford Hall. Recording one person performances is one thing but to get crisp beautiful sound when there are horns, a string quartet, vocals and guitars going is a completely different task. The specific band I am referring to is Mother Falcon.
Mother Falcon is a 20 person chamber pop band, yes this sounds weird but in fact they are one of my favorite bands. The members play many different instruments and tend to be a loud band. Yet when they were invited into NPR the only recording device I could see was a single shot gun mic placed a few feet in front of them. The sound for this performance was impeccable. Granted they are a very professional radio station but still an impressive feat nonetheless. The link below is to Mother Falcons performance and though it may not seem very interesting I strongly suggest you watch it purely for the example of pristine audio recording. I will also post a link to the Macklemore Tiny Desk Concert if that seems more appealing.
I hope you enjoyed my little rant along with the awesome web series that NPR produces.
